SPECIFICATION torturing; part of Letters Patent No. 696,588, dated April 1, 1902. Application filed October 2,1901. Serial No. 77,268.' (No model.)

To all whom it may concern.-

Be it known that I, FRANKLIN J. PERKINS, a.

citizen of the United States, residing in Woburn, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Machines for Treating Hides or Skins, of which the following description, in connec-v tion with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a machine for treating hides and skins, and is herein shown as embodied in a machine particularly adapted for fieshing and unhairing hides and in which a bodily-movable roll cooperates with a bed-roll and with a feed-roll. The invention has for its object to provide a simple and efficient machine for the purpose specified and one with which the operator is relieved from strain and work, as will be described. For this purpose thebodily-movable roll is operated by a cam-shaft, the rotation of which is positively controlled by the operator and the rotation of the said bed-roll and feed-roll is automatically controlled by the said camshaft, as will be described. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a front elevation,with parts broken away, of a machine embodying this invention; Fig. 2, a side elevation of the machine shown in Fig. 1 looking toward the right; Fig. 3, a plan View of the machine,

shown in Fig. 1, and Fig. 4 a detail to be referred to.

The framework of the machine, compris:

partsj is, suitably secured together, so as to move as one piece under certain conditions, as will be described, and yet permit one of said parts to move independent ofthe other underother conditions. Each part 7c is mounted to slide on a side frame of the machine and is secured thereon by bolts orscrews Z, which are extended up through suitable slots on in the side frame and tappedintothe part it, as shown in Fig. 2. The part j of the carriage is mounted to slide on the part 7.: and is secured to the part It to move therewith, as herein shown, by means of a bolt 72, which is tapped into the front end of the part j and extends loosely through an externally-threaded sleeve 0, which engages a threaded opening in an upturned portion 2 of the part 70.

The bolt n is provided with a nut or head g, which bears against the sleeve 0, so that when the part 7t is moved in one direction, as indicated by the arrow 4-0, the part will be moved simultaneously therewith, and when the part 7,: is moved in the opposite direction the partj willbe moved simultaneously therewith by reason of the bolt-head q being kept in engagement with the sleeve 0 by a spiral spring 1*, which latter enables the partj to be moved independent of the part 7; and serves to hold the hide on the bed-roll into engagement with the knife-cylinder witha yielding pressure.

The partj of the carriage also supports the boxes or bearings s for the feed-roll t, the said boxes or bearings being mounted on the part j so as to slide thereon and to move independent thereof by the bolt 6, sleeve 7, and spring Sin a manner similar to that described with relation to the part 3'. The feed-rollt and the bed-roll h are located on the partj of the carriage a distance apart substantially equal to the diameter of a roll 9, which in accordance with this invention is bodily movable with relation to the feed-roll i and the bed-roll h. This bodily movement of the roll 9 may be effected, as herein shown, by supporting the roll at each end by a link or arm 10, which is joined at its-"lower end by the pivot-pin 12 to the end of a leverlS, pivoted, as at 14, to a side frame of the machine and frames or Z) and also in the frames 0 and d.

provided with a segmental gear 15, which meshes with the rack-teeth 16, made in the under side of the part 7c of the carriage.

The links 10 and the levers 13 are joined by connecting-rods 17 with the cranks 18 of a crank-shaft 19, having hearings in the sidIe t will he noticed that the opposite ends of the roll 9 are connected by the-links 10 and the levers 13 to the crankshaft 19, as clearly shown in Fig. 1.

By reference to Fig. 2 it will be seen that in the revolution of the crank-shaft 19 upward movement of the connecting-rods 17 will produce an upward movement of the links 10 and apivotal movement of the levers 13 about their pivots 14. The upward movement of the links or rods 10 lifts the roll 9 bodily away from the bed-roll and feed-roll 23,

while the pivotal movement of the levers 13 effects a movement of the carriage carrying the said rolls in the direction indicated by the arrow 40 away from the knife-cylinder and into what may be termed the starting may also hecarried backward to obtain a sufficient opening between the said roll and the bed-roll to enable the operator to readily insert the hide into its operative position.

After the hide has been inserted into its operative position the roll 9 is moved downward, so as to grip the hide between thefeed rollzf and the bed-roll h, while at the same time the carriage is moved backward into its operative position with relation to the knifecylinder. The movement of the roll 9 and of the carriage may and preferably will be intermittent and placed under the control ofv the operator, and in the present instance I; have shown the machine as provided with a foot-treadle 21, provided with a crank or arm 22, which is joined by a connecting-rod 23 with a crank or arm 24: on a rock-shaft 25, supported in suitable bearings 26, attached to the base e of the framework. The rock shaft 25 is provided with an arm 27, earrying a roller 28, which cooperates with one face ofa cam-hub 29, fast on the cam-shaft 19,

the said cam-hub being provided on one side or face with a projecting flange 30, which is provided at substantially diametrically opposite points with slots 31 32, (see Fig. 4,) into which the roller 28 is adapted to enter at halfrevolutions of the cam-shaft 19. The revoluclutch mechanism, shown in the present instance as a pivoted dog 37, which when engaged by the beveled end of the clutchhub 35 is adapted to render a gear 38 fast on the main shaft 36, the gear 38 being in mesh with the gear 39, fast on the cam-shaft. The main shaft 36' may be continuously rotated by means of a belt 41, passed about a pulley 42, fast on the said main shaft.

From the above description and. by reference to Figs. 1 and 3 it will be seen that when the foot-treadle 21 is depressed the rock-shaft 25 is moved so as to disengage the roller 28 from one of the slots-for instance, 32- -iu the cam-hub 29 and simultaneously move the clutch-hub 35 into engagement with the dog or lever 37, thereby rendering the normally loose gear 38 fast 011 the main shaft 36 and effecting rotation of the cam-shaft 19. As soon as the cam-shaft 19 is set in inotionthe operator may remove his foot from the treadle 21, as the latter will be preventedfrom rising by reason of the engagement of the roller 28 with the flange 30 of the cam-hub until the cam-shaft has made a half-revolntion,at which time the slot 31 willbe brought into line with the roller 18 a'ndwill permit the counterweight 45 to elevate the treadle 21 and move the rock-shaft 25 in the opposite direction, so

as to withdraw the clutch-hub 35 from engage ment with the clutch lever or dog37, thereby rendering the gear 38 again loose on the m'ain shaft 36 and stopping rotation of the camshaft 19. At this time the roll 9,whieh may and preferably has the function of a pinch and feed roll, is operated as above described and the carriage supporting the bed-roll is moved forward in the direction indicated by the arrow40. The operator can then place a hide or skin over the bed-roll and between it and the knife-cylinder andadjust the hide into the desired or proper position,af ter which he again depresses the treadle 21, which rocks the shaft 25, as above described, and again renders the gear 38 fast on the main shaft,

thus again setting the cam-shaft 19 in rotation until it has made a half-revolution or until the slot 32 in the flange 30 of the camhub is brought into line'with the roller 28, at which time the cam-shaft 19 is rendered stationary. During the half-revolution of the cam-shaft as above described the pinch-roll 9 is lowered to engage the hide or skin between it and the feedrollt and the bed-roll it, while at the same time the carriage is movedbaekward into position to permit the hide or skin to be operated upon by the knife eylinder, which position is determined by an adjustable stop, shown as a bolt 50, attached to the part j of the carriage and adapted to engage the stationary frame of the machine. At or about the time the slot 32 in the flange of the cam-hub engages the roll 28 a camgroove 51 in the periphery of the cam-hub 29 operates a clutch-lever 52, so as to move a clutch-hub 53 (see Fig. 3) into engagement ICC with a clutch lever or dog 54, and thereby render a sprocket-wheel 55 fast on the main shaft 36. When the roll 28 engages the slot 32, the shaft is rocked so as to disengage the clutchehub froin-the clutch dog or lever 37, thereby rendering the gear 38 loose on the main shaft 36 and stopping rotation of the gear 39 and CfHIlShflfli 19 at or'about the time the clutch dog or lever 54 is locked to the main shaft 36. The sprocket-wheel 55 is connected by a link chain 56 with a sprocket-wheel 57, which is loose on the cam shaft 19 and which has attached to its hub a second sprocket-wheel 58, (see Fig. 1,) which is connected by a. link chain 59 with a sprocket-wheel 60 on the feed-roll t. It will thus be seen that the cam-groove 51 renders the sprocket-wheel 55 fast on the drivingshaft 36 and through the gearing above (le scribed rotates the feed-roll t, which latter is also provided with a gear 62, (see Fig. 1,)

which meshes with a gear or-pinion G3 on the pinch-roll 9, the gear or pinion 63 meshing with a gear 64 on the bed-roll, so that the feed-roll t, pinch-roll 9, and the bed-roll hare rotated to feed the hide forward or in the direction indicated by the arrow 40. The feedrolls and the bed roll are thus positively driven from the main shaft 36 as long as the cam-hub 29 maintains the sprocket-wheel 55 clutched to the shaft 30. When it is desired to stop the machine, the operator again depresses the treadle 21, which, as above described, connects the cam-shaft with the driving-shaft through the gears 38 39 and produces a half-rotation of the cam-shaft 19, during which time the sprocket-wheel 55 is unclutched by means of the cam-groove 51 in the periphery of the hub 29 and the carriage is moved forward and the pinch-roll 9 elevated into its starting position.

From the above description it will be seen that the operator is not obliged to keep his foot on the treadle while the hide is undergoing treatment, and therefore he is relieved from a very considerable Work and strain, inasmuch as he is only required to depress the treadle to stop the machine and to depress it again to start the machine in operation. He can thus move away from his machine or around it and give his entire attention to the manipulation of the hide or skin.

It will be observed that the rotation of the cam-shaft is positively controlled by the operation of the foot-treadle, whereas the operation of the machine proper-namely, the feed-rolls and bed-roll--is automatically controlled by the cam on the cam-shaft.
